796 * Description: Test the address bus wiring in a

803 * address and size of the region are
804 * selected by the caller.
806 * Notes: For best results, the selected base
807 * address should have enough LSB 0's to
808 * guarantee single address bit changes.
809 * For example, to test a 64-Kbyte
810 * region, select a base address on a
811 * 64-Kbyte boundary. Also, select the
812 * region size as a power-of-two if at
